Any idea what the difference between a NB-1LH battery and a NB-1L battery is?

The Canon S200 Elph that I just bought came with a NB-1LH battery. The documentation says it can use a NB-1L. Any idea what the difference between the two is...besides the "H" on the end of the former one?

i think the ending in H is found on a S400. I think it's a newer battery. It might be rated for more juice as well.
